In the present study we characterized in detail the expression of aromatase P450 in leiomyomas to determine the role of in situ estrogen in the growth advantage of leiomyomas. The levels of aromatase P450 transcripts were determined by quantitative RT-PCR to be significantly higher in leiomyomas than in corresponding myometrium. The overexpression of(More)
The CYP19 gene encoding aromatase P450 (estrogen synthetase) is expressed in several extragonadal sites and regulated in a tissue-specific fashion, which is achieved by alternative use of the seven different promoters (and corresponding exons 1) of the CYP19 gene. Previously, we demonstrated that aromatase P450 is overexpressed in leiomyoma tissue and that(More)
AIM A number of studies for the measurement of cell-free fetal DNA in maternal blood have been reported; however, their clinical significance has remained unclear. We proposed to clarify the relationship between fetal DNA levels and obstetrical disorders. METHODS One hundred and eighty-five cases of normal pregnancy, ranging from 8 to 40 weeks' gestation,(More)
We have shown that in situ estrogen synthesized in leiomyoma of the uterus plays a possible role in the promotion of leiomyoma cell growth via an autocrine/paracrine mechanism. In the present study, we demonstrated that leuprorelin acetate, a GnRH agonist widely used for treatment of uterine leiomyoma by down-regulation of pituitary-ovarian function,(More)
Endometriosis is an estrogen-dependent disease of women of reproductive age. Recent studies demonstrate that endometriosis per se express high levels of estrogen synthetase (aromatase P450). The resulting estrogen synthesized in situ may play a role in the development and exacerbation of the disease. For ovarian endometrioma, previous studies have been(More)
Fetal human osteoblast-like cells and the THP-1 cell line that differentiates into macrophage/osteoblast-like cells in the presence of Vitamin D3 and which possesses high aromatase activity, constitute a useful model with which to study the regulation of aromatase in bone. We showed that dexamethasone (DEX)-induced aromatase activity in the THP-1 cell line(More)
In cases of cervical incompetence, the Shirodkar procedure is occasionally necessary when the McDonald procedure cannot be used due to poor cervical anatomic conditions. We have further facilitated a modified Shirodkar procedure with some modifications. A transverse incision over the anterior lip of the cervix is made and the bladder is separated from the(More)
BACKGROUND Reliable leak-proof aspiration of cyst contents is required for treatment of large ovarian cysts by minilaparotomy. TECHNIQUE Through a small abdominal wound a transparent plastic bag was instantly mounted onto the cyst surface using an ethyl-2-cyanoacrylate adhesive. A 1-2-cm-wide cut was made in the consolidated cyst wall through the inside(More)
